javascript - jQuery Mobile showing doubled button -


i'm trying first app jqm+phonegap.

here's code:

as can see simple page.

the problem outputs double button instead of 1 , it's driving me mad.

replacing 

<a onclick="$(this).toggleclass('toggleoffbutton');" data-role="button" class="toggleonbutton" id='togglebutton' data-corners="true" data-mini="false" data-theme="a" tabindex="2"/>

with string makes print string 1 time intended button repeated twice.

any ideas on can problem?

i reading including twice jqm scripts but, can see in code, they're not double referenced!

i have tested html , found problem.

jquery mobile button created tag element must closed. change this:

<a onclick="$(this).toggleclass('toggleoffbutton');" data-role="button" class="toggleonbutton" id='togglebutton' data-corners="true" data-mini="false" data-theme="a" tabindex="2"/>

to this:

<a onclick="$(this).toggleclass('toggleoffbutton');" data-role="button" class="toggleonbutton" id='togglebutton' data-corners="true" data-mini="false" data-theme="a" tabindex="2"/></a>

also give text.

and omar told in comments don't need:

<link rel="stylesheet" type="text/css" href="css/jquery.mobile-1.3.1.min.css" />

if have these files:

<link rel="stylesheet" type="text/css" href="css/jquery.mobile.structure-1.3.1.min.css" /> <link rel="stylesheet" type="text/css" href="css/jquery.mobile.theme-1.3.1.min.css" />
